Hello, anybody there?

Of course the problem with a blog is that it's a bit one-way traffic. You write things, but you don't really know if people read them. Yes, we have a 'stats' feature on blogspot which tells us how many page views there were and from which countries, but there is not a lot of detail!
Yesterday I issued a little challenge and I only got ONE response (by email, that was nice to get!). So who is actually reading this??
Now the challenge is still open: what does that sign mean? Answers via email (for those who know my email address) or via 'comments'.

We are now in Bremerhaven. The second half of the Geeste was very quiet, we saw two other boats. When we got out of the lock at Bremerhaven, we were back on tidal water. It was just past low tide and the river looked very different from when we left here on 16 June. The wooden structures you can see in the picture were under water then. The 'prikken' (the wooden branches to mark the underwater obstruction) are just visible, tied onto the wooden 'frames'. You have no idea what's under the surface!





Tomorrow, we'll have our final tidal stretch, up the Weser and the Hunte to Oldenburg. We'll leave Bremerhaven at low tide, around noon and let the current help us up the rivers.
